POWER TRANSMITTING APPARATUS.

APPLIUATION FILED DEC 19.1905. 973,865, Patented Oct. 18,1910.

by heavy channel-members 19 held in place as by suitable brackets 20 and21, and upon these cross-members is mounted an engine bed 22 and engine23, preferably of the internal combustion type. Crank-shaft 24 of theengine is preferably provided with a sprocket-wheel 25 connected as bysprocketchain 26 with a similar wheel 27 upon the axle 11, this form oftransmitting mecha nism being found peculiarly adapted for use in therelation shown, although other connections may be used and many of theadvantageous features of my invention retained.

As shown in Fig. 1 of the drawings, the engine 23 Pprojects within thebody of the car throng a suitable opening in thefloorframe thereof andthe cylinders 28, with the controlling mechanism 29 mounted thereon, arethus brought within convenient reach of the engineer without sacrificingefliciency in the matter of the location of the crankshaft, the openingin the floor frame being, as clearly shown in the drawings, sufiicientlylarge to permit any desired relative movement ofthe engine with respectto the carbody. It may here be noted that the term controllingmechanism, as used herein with relation to the parts diagrammaticallyrepresented at 29, is intended to cover any device or devices by whichthe action of an portion of the engine is modified. Upon an e 11 isloosel mounted a sleeve 30 upon which is loosefy journaled thesprocketwheel 27 having secured thereto what may be termed a carrier 31extending in a plane transverse to the axle as shown in ig. 3. Carrier31 is provided with an inwardly directed flange 32 adapted to be grippedor clamped by the clutch-members 33 and 34 disposed u on each sidethereof. Clutch-member 33 is heyed to the sleeve 30 i and is rovidedwith bolts 35 passing loosely 'throug the clutch-member 34 and havingheld upon their outer ends as by lock-nuts 36 the recessed collars 37.Fitting within these collars and taking against recesses 38 in theclutch-member 3 1 are actuating levers 39, the outer end portions 40 ofwhich are, in general, of the elliptical form shown and the inner endsof which are secured in any desired manner to a sleeve 4]. looselymounted on the axle. It will thus be seen that u on the sleeve 41 beingreciprocated u on the axle, the levers 39 which lie in a p anesubstantially parallel to that of the carrier 31 are given aswingingmovement, resulting in the elliptical ends 10 thereof moving apart, orpermitting to draw toether, the collars 37 and the opposite surace ofthe clutch-member 34. This move-,

ment, assuming the levers to be thrown in such direction as to bring themajor axis of their elli tical ends niore nearly into alinemeet wit thepelts 35,'will cause the clutchmember to be thrown toward the flange 32and the clutcl'i-member to be drawn outwardly toward the same part bymeans of the bolts, thus clamping this flange and completing thepower-transniitting means from the sprocket-w]reel 27 to the sleeve 30.Upon the actuating lovers 39 being thrown by sleeve 41 intthe oppositedirection, however, the outward pressure upon the collars 37 is relievedand lost motion bci 'g taken up as by springs iiifthe clutch-mcmbers 33and M are forced apart, releasing the flange 32. The throwing of sleeve41 is preferably accomplished by means of a loose band 43 fitted withina groove therein and provided with trunnions 44 lying within slots intheend of a forked lever 45, pivoted as at 4:6 to a rigid frame 47 looselymounted upon the sleeve 30 at 48 and upon the axle 11 at 49.

Lover is provided with an extension 50,

projecting up into the car and may, if de sired, be actuated thereby andheld in position as by a locking segment 51, although in the preferreduse of my inventionI mount a cylinder 52 upon the frame 47 and, byproper regulation of the pressure within the respective ends thereof,control through the piston-rod 53 the position of the lever. It will beseen that by the disposition of the parts as above extends, broadlyspeaking, in a plane transverse of the axle, and it is to be understoodthat expressions defining this disposition of the friction clutch areintended to be broadly construed as covering a general disposition ofthe parts in or near such a plane.

Fixed upon sleeve 30 upon the opposite side of sprocket-wheel 27 fromthe clutch mechanism above described is a gear 54 meshing with the gear55 upon a counter-shaft 56 journaled within an extending portion 57 ofthe frame 47. -This extension is resiliently mounted upon an end bar 58of the truck frame, as by means of the depending rods 5.) passingthercthrough, and the springs 60 and (31 disposed upon these rods.Mounted upon shaft 56 is a second gear 69. meshing with a, gear 3loosely mounted upon the axle 11 and provided with a clutch-member (S 1oppositely disposed to a similar part set forth, the friction clutchupon the first-mentioned gear 54. Keyed '67 loosely clamped about thesome and pro- 11$ use of the several feacures thereof is subfriction-clutch is then thrown in, either by changed by means of thepositive clutch,

clutch, but: is preferably iu'complishml by vided withlrunnions 68taking into sloi'zs in the end of a forked-lover 69 pivoted it 70 tothe-fmme Lever 69 is preferably provided with on extension 71 passingupwardly into the car-body and. permitting these parts to be thrown byhand, but in the preferred use of my invention ipi'ovicie iicylinder 72,mounted upon the frame 47, similar in construction and funcl ion tocyls' indcifiQ above described.

The operation of the obovedescribed em bodimcnt of my invention andmethod of stant-iallv as follows:

Assuming the clutch-member '66 to be in mid position and the flange 32'lo free from the enacting clutch-members ii ii be desired to start thecar the engine is first put in motion and the cluiolrmen'ibcr throwninto engagement with either clutchmember or clutch-member (34, accordinghigh or low speed of driving desired, it being understood that by meansof "the gearing upon sheila 56 the gears 54 and 63 are driven at diiierent rates of speed. The

power or by in manual actuation of the lever 45, and )ower is thustransmitted the engine through the sproclrebchain and friction-clutch tothe sleeve 30 from which it passes through the gear 54 direct to member66 and thence 'io axis 11 or through the oounter-shnft and gears 55 and63, accordingto the position of the doublefaced clutch member, andthence through the latter part lo the axle 1i and wheels 13. hen it isdesired to change the speed, the frictioncluich is first thrown out andthe speed whereupon the friction-clutch is again thrown in, thus greatlyreducing the strain upon the teeth of the positive clutch by res.- Sonof the fact that the parts into engagemen with which ii thrown orceilherrein ti'vely stationary or their relative movement is that due toinonicntxun only. lho shock, moreover, is still further rcduccd byreason i of the resilient suspension of the ironic 4-7 whereby thecounter-swift .36 will) the gears mounted ihercon may swing to n slightcent about the axle as'n center and thus further cushion the action ofthe parts. The vehicle may be brought to a standstill either by stoppingthe engine, throwing out the friction-clul'cli or throwing outthc'posil'ivc the second-mcut-ioncd moans. lly reason of the severalways in which the car may be brouoht to a standstill, however it willreadily be seen that this may be ncconn plished with a. quickness andcertainty which might be otherwise impracticable.

"It will. thus be seen that I have provided apparatus well adapted toaccomplish the several objects of my invention and that this is of thesimplest and most compile; con? sir-notion. The engine is resilientlymounted upon the arc es, i'hus avoiding the execs 'ive jar to thesomewhat delicate mechanism thereof which would be occasioned by theabsence of cushioning means between these ports. it is, nevertheless, somounted with relation to the axle 2155 not only to reduce the lengih oitransmission to a minimumconsisient Wl'l'l'i cliicient action, but to beso disposed as to move only slightly with reference thereto. Thecylinders of the engine, moreover, with their controlling mechanismproject within the can so as to be instantly accessible in the engineerand yet do nol interfere with the mounting oi? the car-body in suchmanner as to have the easiest, riding qualities on account of theinterposition of the sprii'igs l7 bciween lbc car-body and theilllClI-llll'lllllfi. The advantages of this ioni'nre are more clearlyappnrcni in View of ihediliiculties which would arise in providenefficient transmission between the axle and the car-body ii the latterwere inounlcd with suilicicnt resiliency to have the desired ridingqualities and the engine were positioned within the car. Thel'rni'isinitling mechanism mounted upon the axle, moreover, is socompactly disposed as readily to be positioned upon :1 single drivingaxle and yet is of the most eiiiciem'i character. On account of thecontrolling menus projectingfrom the transmission upon the axle into thecar, will be seen that these parts are. not only within convenientrcnclrof i'ho. engineer, but- :u'c, together with the engine, so groupedshot all fcaiures of the powergcncrnling' and conlrolling ap 'mrnius iswithin instant reach oi. :1 single man. Another fcnturc to whichattention should be called in this com'icction is the peculiaradaptability oi the entire nppnrniius described for use in connectionwith a motor car ndnpl'ed to travel upon rails and to be propelled all;a high rate of speed. The entire apparatus is thus of The simplest andmost cilicicnii construction and, by reason. of these features.l'ogci'her will) its ease of control, is well adapted to meet therequirements oi practical use in the nbovc-noted relation.

As many chanlges could be made in the above coi'isliuction and manyapparently widely diflcrent embodiments of my invenlion could be madewithout departing from the scope thereof, lintend lhiil: all matterconl'iiined in the above description or shown in the ncconn'innyingdrawings shall be interpreted. as illustrative and nol; in a limitingsense.
